Definitions
- Active seating allows a user freedom of movement while remaining seated. For example, a user may be able to pivot, rotate, or otherwise move the seat while sitting in the seat.
- Other seating includes pedals or other structures that can be moved by the user while the user remains seated. Improvements are desired.
- Some aspects of the disclosure are directed to an active seat allowing a user to tilt in one or more directions.
- an active seat could be used in a classroom setting, a daycare, or at home.
- Two or more active seats can easily stack together for compact storage.
- an active seat includes a seat disposed at a first end of a body; a convex surface disposed at a second end of the body; and a stacking notch defined at an intermediate location along the body between the first and second ends.
- the convex surface defines at least a first rocking path about which the active seat tilts.
- the stacking notch defines a flat surface extending along part of the length of the body.
- the flat surface is recessed laterally inwardly from an outer periphery of the body taken at the first and second ends.
- the convex surface defines a plurality of rocking paths.
- at least one of the rocking paths is rotationally offset from another of the rocking paths.
- at least one of the rocking paths is laterally offset from another of the rocking paths.
- the active seat is monolithically formed. In other examples, at least the convex surface is formed from a separate piece than the seat. In certain examples, the active seat is fabricated from a first monolithically-formed body defining the seat and the stacking notch and from a plate coupled to the body.
- multiple active seats can be stored in a stacked configuration.
- adjacent active seats are oriented at 90 degree rotational offsets from each other while aligning the flat surfaces to oppose each other.
- the active seats define resting surfaces that contact either the floor or resting surface of a supporting active seat to enhance stability of the stack.
- inventive aspects can relate to individual features and to combinations of features. It is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the broad inventive concepts upon which the embodiments disclosed herein are based.

- the present disclosure is directed to a stackable active seat.
- an example active seat 100 extends between a first end 102 and a second end 104 .
- the active seat 100 includes a first end portion 110 , a second end portion 112 , and a connecting portion 114 .
- the first end portion 110 defines the first end 102 of the active seat and the second end portion 112 defines the second end 104 of the active seat 100 .
- a seating surface 118 is disposed at the first end portion 110 .
- the seating surface 118 is flat. In other implementations, the seating surface 118 is contoured. In some examples, the seating surface 118 is formed by a depression in the first end portion 110 . In other examples, the seating surface 118 has portions raised above the first end portion 110 . In the example shown, the seating surface 118 is integral with the first end portion. In other examples, the seating surface 118 may be a separate piece mounted to the first end portion 110 . The seating surface 118 faces in a first direction.
- a convexly contoured surface 120 is disposed at the second end portion 114 .
- the convexly contoured surface 120 faces in a second direction that is opposite the first direction.
- the convexly contoured surface 120 defines at least one rocking path R 1 along which the active seat 100 can tilt. Tilting the active seat 100 along the rocking path translates the seating surface 118 along a corresponding tilting path T.
- the convexly contoured surface 120 defines multiple rocking paths (e.g., see rocking paths R 1 , R 2 , and R 3 ) along which the active seat 100 can be tilted.
- the rocking paths are rotationally offset from each other (e.g., compare rocking paths R 1 and R 2 ), thereby allowing a user to rock along different directions (e.g., forward-rearward, side-to-side, etc.).
- the rocking paths are laterally offset from each other (e.g., compare rocking paths R 1 and R 3 ), thereby allowing the user to rock back and forth at different lateral tilt angles.
- three example rocking paths R 1 , R 2 , R 3 are shown.
- the convex surface 112 is oblong. In other examples, the convex surface 112 may have other contoured shapes (e.g., a spherical cap).
- the active seat 100 tilts along a rocking path R 1 , R 2 , there is a change in angle ⁇ between the longitudinal axis L of the active seat 100 and a reference axis normal to a floor F on which the stool is disposed.
- the active seat 100 is shown in solid lines tilted to a furthermost position along the rocking path R 1 , R 2 in a first direction and is shown in dashed lines tilted to a furthermost position along the rocking path R 1 , R 2 in a second direction that is opposite the first direction. It is noted that the active seat 100 can tilt along any of the rocking paths defined by the convex surface 112 .
- the convex surface 120 allows the active seat 100 to tilt up to an angle of 45 degrees in either direction along the rocking path R 1 . In certain implementations, the convex surface 120 allows the active seat 100 to tilt up to an angle of 40 degrees in either direction along the rocking path R 1 . In certain implementations, the convex surface 120 allows the active seat 100 to tilt up to an angle of 35 degrees in either direction along the rocking path R 1 . In certain implementations, the convex surface 120 allows the active seat 100 to tilt up to an angle of 30 degrees in either direction along the rocking path R 1 . In certain implementations, the convex surface 120 allows the active seat 100 to tilt at an angle of between about 5 degrees and about 45 degrees in either direction along the rocking path R 1 .
- the convex surface 120 allows the active seat 100 to tilt at an angle of between about 10 degrees and about 35 degrees in either direction along the rocking path R 1 . In certain implementations, the convex surface 120 allows the active seat 100 to tilt at an angle of between about 15 degrees and about 25 degrees in either direction along the rocking path R 1 .
- the convex surface 120 is integral with the second end portion 112 .
- the convex surface 120 is a defined by a separate piece 140 that is mounted to the second end portion 112 (e.g., see FIG. 4 ).
- the separate piece 140 may define one or more fastener openings 142 through which fasteners (e.g., screws) may be disposed to hold the separate piece 140 to the second end portion 112 .
- the separate piece 140 is formed of a different material (e.g., a more rigid material, a stronger material, a differently textured material, etc.) than the second end portion 112 .
- a part 134 of the second end portion 112 extends laterally outwardly beyond the convex surface 120 .
- This part 134 provides a stop surface that inhibits further tilting of the active seat 100 along the rocking paths R 1 , R 2 , R 3 .
- the part 134 defines a periphery around the separate piece 140 .
- the part 134 is integral with the second end portion 112 .
- the connecting portion 114 extends between the first end portion 110 and the second end portion 112 .
- the connecting portion 114 defines oppositely facing flat surfaces 122 .
- the flat surfaces 122 are connected by oppositely facing side surfaces 124 .
- the side surfaces 124 are convexly curved. In other examples, the side surfaces 124 can be flat or concavely curved.
- the connecting portion 114 has a transverse cross-dimension that is less than a transverse cross-dimension of the first end portion 110 and is less than a transverse cross-dimension of the second end portion 112 . In certain examples, any transverse cross-dimension of the connecting portion 114 is less than the corresponding transverse cross-dimensions of the first and second end portions 110 , 112 .
- the active seat 100 has an I-shaped profile. In certain examples, the active seat 100 has an I-shaped profile in a first orientation and in a second orientation that is rotated 90 degrees from the first orientation.
- the first end portion 110 is shaped the same as the second end portion 112 .
- the first and second end portions 110 , 112 are similarly sized and shaped, but are not the same.
- the first and second end portions 110 , 112 contour or taper outwardly as they transition away from the connecting portion 114 .
- the active seat 100 is configured to enable multiple active seats be stored in a stack. To stack the active seats 100 , a first active seat 100 is flipped 90 degrees to lie sideways on the floor F.
- the first and second end portions 110 , 112 define resting surfaces 126 , 128 , respectively, that contact the floor F when the active seat 100 is laid sideways on the floor F.
- the resting surfaces 126 , 128 are flat. In other examples, the resting surfaces 126 , 128 can be concave or slightly convex.
- each of the first and second end portions 110 , 112 defines oppositely facing resting surfaces 126 , 128 .
- the active seat 100 is oriented on the floor so that one resting surface 126 of the first end portion 110 and one resting surface 128 of the second end portion 112 lie on the floor F. In such an orientation, a first of the flat surfaces 122 faces the floor F and the second flat surface 122 faces away from the floor F. A second active seat 100 is then oriented sideways so that it has a first flat surface 122 aligned with and facing the second flat surface 122 of the first active seat 100 . However, the second active seat 100 is rotated 90 degrees relative to the first active seat 100 (e.g., see FIG. 5 ). Accordingly, the resting surfaces 126 , 128 of the second active seat 100 face the floor F, but do not align with the resting surfaces 126 , 128 of the first active seat 100 .
- the second active seat 100 is laid over the first active seat 100 so that the first flat surface 122 of the second active seat 100 is supported by the second flat surface 122 of the first active seat 100 (e.g., see FIG. 6 ).
- the first and second end portions 110 , 112 of the second active seat 100 are rotationally offset from the first and second end portions 110 , 112 of the first active seat 100 .
- the first active seat 100 holds the first and second end portions 110 , 112 of the second active seat 100 off the ground F.
- the third active seat 100 can have the same orientation as the first active seat 100 (e.g., see FIG. 5 ) or can be flipped 180 degrees relative to the first active seat 100 (e.g., see FIG. 7 ).
- downward-facing resting surfaces 126 , 128 of the second active seat 100 rest on upward-facing resting surfaces 126 , 128 of the first active seat 100 .
- first resting surfaces 126 of the first and second active seats 100 contact each other and second resting surfaces 128 of the first and second active seats 100 contact each other. If oriented as shown in FIG.
- a first resting surface 126 of the first active seat 100 contacts a second resting surface 128 of the second active seat 100 and a second resting surface 128 of the first active seat 100 contacts a first resting surface 126 of the second active seat 100 .
